About
Changjae Lee is an emerging researcher at the intersection of human-computer interaction, computing education, and computational thinking. Their work centers on designing innovative programming interfaces and learning tools that make complex problem-solving more accessible to novice learners. Lee's most notable contribution to date is **Spark**, a multimodal programming interface developed to help beginners externalize decomposition thinking — the cognitively demanding process of breaking complex problems into smaller, manageable components. This research bridges the gap between visual and multimodal programming paradigms, reflecting a deep commitment to lowering barriers for those new to coding and computational reasoning. Lee's approach is distinctive in its emphasis on the *cognitive* dimensions of learning to program, not merely the technical ones. By designing tools that make invisible thinking processes visible, their work addresses one of the most persistent challenges in computing education. Though early in their research career — with publications appearing in 2026 and a growing citation record — Lee's focus on computational thinking scaffolding positions them within a timely and increasingly important field, as educators worldwide grapple with how to teach programming concepts meaningfully and equitably to diverse learners.
